Xinjiang Yizhuang's scientific research achievement reaches the world's leading level

Changji Daily (all -media reporter Sun Xueliang correspondent Feng Liang) Recently, the reporter learned from Xinjiang Yizhou Chemical Co., Ltd. (hereinafter referred to as Xinjiang Yizhe) that the company and the Chinese Academy of Sciences Engineering Institute of Engineering The Institute of Engineering and Hefei Gel Chemical Technology Co., Ltd. The company jointly developed "omnipotent oxygen -enriched cyclic -fluid -based high -alkali gas chemical synthetic gas technology" was appraised by the scientific and technological achievements organized by the China Petroleum and Chemical Industry Federation on September 4th. The technology generally reached the international leading level. It has reached the international leading level in high alkali gas, which is of positive significance for Xinjiang's high -alkaline coal development and development of the local economy.

It is understood that the high -alkali coal in the quasi -east coal field has the characteristics of poor viscosity, poor paste, and high alkaline metal content. Due to high volatile scores, environmental problems are difficult to solve.

"Settlement of high -alkali gas chemical synthetic gas technology in normal pressure -enriched cyclication beds" is based on Xinjiang's quasi -East Coal as the research object. Technological innovation in tube gas sealing dry residue discharge has achieved a significant improvement of system gasification efficiency, overall energy efficiency of the system, and the reliability of gasification furnaces, reduce wastewater discharge, and solve the problem of coking oil and phenol -containing wastewater pollution.

"This technology has a strong adaptability to the raw coal ash melting point, and the process is simple. You can use quasi -east high -alkali powder as raw materials and do not need to make powder. Gas and wastewater do not contain caramel and phenol. Chief engineer Yang Xiaoqin said.

As one of the key coal chemical enterprises in Xinjiang Junior East Economic and Technological Development Zone, Xinjiang Yizhou Chemical is mainly produced by producing synthetic ammonia, urea, melamine and other products. Since 2019, the company has upgraded the synthetic ammonia production line, and has invested 380 million yuan to build 3 newly -permeable oxygen -rich cyclic -fluidized bed gasification devices to replace the original 20 normally pressure -rich fixed bed continuous gasification devices. Taking the company's self -produced high -alkali coal as the raw material, it is made of synthetic qi, producing synthetic ammonia, urea, melamine, etc. By continuously developing and optimizing, the long -term operation of the device is stable.

"Compared with the previous, the cost of producing ammonia using this technology is reduced by 400 yuan per ton, and the economic benefits of the annual creation of 160 million yuan. At the same time, it can reduce the energy consumption of 95,000 tons. The solid waste is 150,000 tons, and economic benefits and social benefits are very significant. At present, this technology has obtained 5 national authorized invention patents and 2 practical new patents. "Yang Xiaoqin said.
